[0001] The utility model relates to the technical field of printing and dyeing water treatment, in particular to a printing and dyeing water circulation and reuse device. Background Art

[0002] The printing and dyeing industry is an important link in the textile industry chain. It involves the application of various colors and the printing of patterns, thus giving textiles a unique aesthetic value. However, the printing and dyeing process involves multiple water-consuming links, such as washing, rinsing, dyeing, etc. Traditional printing and dyeing processes usually consume a lot of water, especially in the washing and rinsing stages, which require a lot of water for dilution and cleaning. At the same time, many printing and dyeing companies do not effectively recycle water, resulting in a large amount of wastewater being directly discharged, and these wastewaters often contain recyclable water resources. In addition, printing and dyeing wastewater usually contains various organic and inorganic pollutants. If not properly treated, it will not only cause serious damage to the ecosystem, but also waste precious water resources.

[0003] The traditional wastewater treatment method is to build a wastewater pool, add an appropriate amount of treatment agent according to the amount of wastewater, stir and mix, let it stand, extract the middle water, and then extract the flocculants. The flocculation process needs to be kept still, so the treatment efficiency is low and is not conducive to recycling. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] See also Figures 1 to 9 In an embodiment of the utility model, a printing and dyeing water recycling device comprises:

[0031] The flocculation reaction mechanism 100 includes a plurality of flocculators 110, a drainage pipe 140 fixed to the bottom of the flocculator 110, and a plurality of electric push rods 130. The flocculator 110 is used for flocculation reaction, and its bottom is fixedly connected to the electric push rod 130; the top of the flocculator 110 is slidably connected to the inner wall of the bottom of the wastewater tank 120, and the legs on the wastewater tank 120 are used for support. The bottom of the flocculator 110 is fixedly connected to the drainage pipe 140, and the drainage pipe 140 at the bottom of the flocculator 110 is used to discharge the flocculated material, and the wastewater is repeatedly discharged. Flocculation operation: A stirring assembly 111 is fixedly connected to the bottom of the flocculator 110, and the stirring assembly 111 includes a shell fixed to the bottom of the flocculator 110. A driving motor is installed inside the shell. The wastewater is stirred by stirring blades connected to the motor shaft of the driving motor and located at the bottom of the inner side of the flocculator 110. The stirring blades at the top of the stirring assembly 111 are located inside the flocculator 110. A through groove 112 is provided on one side of the flocculator 110. The operation of the stirring assembly 111 allows the flocculant and the wastewater to be fully mixed, thereby accelerating the flocculation reaction.

[0032] Specifically, the delivery mechanism 200 includes a flocculant release assembly 210 and a cover plate 220, which are located on one side of the flocculation reaction mechanism 100, the middle of the flocculant release assembly 210 is fixedly connected to the cover plate 220, the bottom T-shaped structure of the flocculant release assembly 210 is fixedly connected to the inner wall of the flocculator 110, the flocculation reaction mechanism 100 and the flocculant release assembly 210 are used for automatic addition of flocculants, and the flocculation reaction mechanism 100 and the cover plate 220 are used for automatic injection of wastewater;

[0033] Specifically, the moving mechanism 300 includes a drain pipe 330 and a grey water pipe moving assembly, and the grey water pipe moving assembly is fixedly connected to the inner wall of the flocculator 110;

[0034] Specifically, the partition 400 includes a pull rope 410, which is rotatably connected to the moving component of the grey water pipe, the partition 400 is rotatably connected to the slider 320, one side of the partition 400 is fixedly connected to the pull rope 410, the other side of the partition 400 is fixedly connected to one end of a tension spring 420, and the other end of the tension spring 420 is fixedly connected to the slider 320. When wastewater enters the flocculator 110, the pull rope 410 is pulled to lift the partition 400. When the flocculation reaction is completed, the pull rope 410 is released, and the partition 400 is lowered under the action of the tension spring 420.

[0035] In the specific implementation, the electric push rod 130 pushes the flocculator 110 to rise, so that the wastewater enters the flocculator 110.

When the electric push rod 130 drives the flocculator 110 to descend, the flocculant release column 212 descends, and at this time the V-shaped groove on the flocculant release column 212 is located in the flocculant temporary storage shell 213, and the flocculant no longer flows into the flocculant temporary storage shell 213, and the square groove on the flocculant release column 212 is located at the bottom of the flocculant temporary storage shell 213, and the flocculant flows from the flocculant temporary storage shell 213 through the square groove and the shell of the flocculant release column 212 into the flocculator 110, and the automatic addition of flocculant is completed.

[0038] like Figure 2 , 6 As shown in Figures 8 and 9, in this embodiment, the grey water pipe moving assembly includes a guide rail 310 and a slider 320, the guide rail 310 is fixedly connected to the inner wall of the flocculator 110, the slider 320 is slidably connected to the guide rail 310, one end of the slider 320 is fixedly connected to one end of the drain pipe 330, the drain pipe 330 is fixedly connected to the slider 340, and the slider 340 is closely attached to the inner wall of the flocculator 110 and can slide thereon.

[0039] During specific implementation, by adjusting the position of the slider 320, the water inlet of the drain pipe 330 connected thereto is located above the interface between the flocculent layer and the middle water layer, so that only middle water flows out of the drain pipe 330. The slide plate 340 is used to block the through groove 112 through which the drain pipe 330 moves. A rubber pad is provided between the slider 320 and the guide rail 310 to keep the vertical position of the drain pipe 330 unchanged after the slider 320 moves.

[0040] In this embodiment, both the sewage pipe 330 and the drainage pipe 140 are provided with valves for controlling the opening, and sewage or drainage is achieved by controlling the opening and closing of the valves. This technology is well known to technicians in this technical field and is a commonly used device in this technical field, so it will not be described in detail here.

[0041] Example 2

[0042] On the basis of the first embodiment, in order to make up for the problem in the first embodiment that the partition plate 400 easily stirs the flow of liquid in the flocculator 110 when rotating.
